I was also having the same problem over the last few weeks with one of my Linux mail servers and it really stressed me. From my research, note these:- - Having/not having reverse DNS records does not contribute to an IP being blacklisted - Changing your server's IP and then the MX records is just running away from the real problem - Most spam generating spyware/malware rarely ever sends out mail through your mail server; your network/router is NATting for a host that's doing spamming on it's own. The solution is initially to clean up your network. Note that normal anti-virus programs even when up to date rarely arrest spamming applications. You need a good anti-malware; try Spyware Doctor Also consider deploying a firewall with a rule that only allows your server's IP to be the only host allowed to send out mail; i.e. a rule that allows outbound SMTP traffic (port 25 and 587 in some instances) from the server only. Hope that helps you. Regards, Martin Mugo On Tue, Jun 29, 2010 at 2:40 PM, Nawaz Bagha <nawazb@gmail.com> wrote:
had something similar in our office... ask your ISP to change your IPs.... and then redirect any AX/MX records to the new IP... And try getting an outgoing mail scanner e.g. Brightmail Gateway... Run a spambot check on the endpoints on your network as well....

The blacklisted IP is a virtual IP and not the mail servers IP. Recently there is alot of outbound traffic to the internet almost nearing the download.

Ask your ISP to do for you a PTR record; mail domain against Public IP. Then go to all sites blacklisting you and whitelist. Some learn from others so if you get whitelisted from others it will take a few days to come out of all lists. Also like they said ensure your network is clean brother.
